PBIMING VALVE.

Application filed January 14, 1921.

To all whom it may concern Be it known that we, Ronnn'r' W. LINLEY andPHILLIP B. LINLnr, citizens of the United States, and residents of Fairfield, in the county of F airfield and State of Connecticut, haveinvented certain new and useful Improvements in Priming Valves, of whichthe following is a specification.

This invention relates to priming cups such as are used in connectionwith gas engine cylinders for the introduction of preliminary charges offuel.

The object of the invention is to provide an inexpensive and practicallyconstructed priming cup, adaptable to various forms of explosiveengines, comprising a reservoir having a cover capable of beingpositioned to afford a large filling opening or to tightly close thereservoir, a needle valve for regulating the flow of fuel fromthereservoir to a gas engine cylinder, a rotatable operating handle formanipulating theneedle valve, simply and novelly constructed connectionsbetween the needle valve operating handle and the cover whereby thecover can be positioned by rotation of the operating handle to open orclose the reservoir.

With the above and other objects in view, the invention resides andconsists in the novel combination and arrangement of parts shown in theaccompanying drawing forming a part of this specification and uponwhich,

Fig. 1 is side elevational view of the priming cup;

Fig. 2 is a vertical sectional view thereof;

Fig. 3 is a section on line 33 in Fig. 1, looking in the direction ofthe arrows;

Fig. 4 is a section on line 4-4 in Fig. 1, looking in the direction ofthe arrows; and

Fig. 5 is a section corresponding with Fig. 4, but showing the cover inopen position.

Referring in detail to the reference numerals marked upon the drawing,10 denotes the main body of the priming valve and 11 the lower threadedplug portion thereof adapted to be screwed into an engine cylinder orotherwise connected therewith as the situation may require. This plugportion 11 includes a drain passage 12 adapted to communicate with areservoir 13 in the lower portion of which is located the preferablbeveled end, denoted by 14, of a needle va ve, said beveled end beingadapted to engage an annular beveled seat 15 Specification of LettersPatent.

formed in body 10 and surrounding the inlet to drain passage 12 beforementioned. The stem 16 of the needle valve includes a threaded portion17 adapted to ride in a threaded hub 18 of the valve body to move thebeveled end from and toward its seat when the valve stem is rotated, aswill be understood. 19 denotes an operating handle fixed in any desiredmanner upon the outer end ofstem 16 and preferably constructed of fiberor other suitable material that will not become hot.

A cover 20, adapted to close the reservoir, is provided with an opening21 to receive the valve stem or its threaded portion. This cover iscapable of being swung upon the valve stem as a pivot to open and closethe reservoir by means of the operating handle in the manner now to beexplained. A coil spring 22, freely positioned about the valve stem andlocated between the operating handle and the cover, has its lowerportion resting against the upper face of the cover to hold the samefirmly upon the valve body and its lower end bent downwardly in aboutthe manner shown to pass through a hole in the cover and to extenddownwardly slightly into the reservoir, as denoted by numeral 23, andits upper portion resting against the lower face of the operating handleand its upper end extending outwardly, as denoted by numeral 24, inposition to be engaged by a continuousseries of protuberances 25extending downwardly from the lower face of the operating handle andlocated about the valve stem at a slight distance therefrom.

The method of operation .is apparent. Suppose the cover and valve areboth in closed position and it is desired to introduce a charge. Theoperating handle of Figs. 1 and 2 is simply turned in left handdirection. The initial turning movement will, through theinstrumentality of the coil spring, cause the cover to open to the position of Fig. 5, the engagement of end 24 with a protuberance 25furnishing suflicient friction to cause the cover to turn with the stem,as will be evident. When, however, end 28 has engaged the wall of thereservoir, as suggested in Fig. 5, the cover cannot be turned further.Continued left hand turning of the operating handle will cause thebeveled portion of the needle valve to recede from its seat, end 24riding over the protuberances. After the charge has been,

vious.

Having thus described the invention, what we claim and desire to secureby Letters Patent is: i

1. A priinin cup-including a reservoir, a valve and val ve stem havingan operating handle, a cover pivoted upon the valve stem "and adapted toclose the reservoir, and a spring upon the valve stem having one of itsends in frictional engagement with the handle audits other end directlysecured to the cover, to open 'and'clos'e the same.

2. A priming cup including a valve body and a valve having a stem, areservoir in the body, a cover for the reservoir, and connectionsbetween the valve stem and cover whereby the cover is frictionallyengaged and turned by the stem in a way to open'or close the reservoir,said connections permitting a further movementof the valve stemindependent of the cover and comprising a spring frictionally supportedfrointhe valve stem, engaging the cover, and adapted to engage the wallof the reservoir.

7 3. A riming cup comprising a body having a uid passage therethrough, avalve having a stem adapted to open and close the .oassage, a reservoirlocated to one side of the valve and connecting with the passage pastthe valve a cover for thereser- V011 and pivoted upon the valve stem, anoperating handle fixed upon said stem, a spring upon the valve stein andbetween the handle and cover, and protuberances upon the handle, saidspring having an end secured to said cover and adapted to engage thewall of said reservoir and an end-adapted to frictionally engage saidproti'iberances, whereby the cover can be made to turn with the valvestem to open or to close the reservoir and the valve stem can havefurther turning movement independent of the cover.
